Description

Technical Field

[0001] This invention relates to the field of grease filling equipment technology, specifically a grease filler. Background Technology

[0002] A grease injector is a specialized power tool used to force high-viscosity grease onto the friction parts of mechanical equipment under high pressure. The main purpose of a grease injector is to perform preventative maintenance and upkeep on various types of machinery to reduce friction, prevent wear, extend equipment lifespan, and improve operating efficiency. It is widely used in many fields such as automobile chassis, construction machinery, industrial production lines, wind turbine generators, and port cranes.

[0003] Existing grease fillers have gradually revealed their shortcomings during use, mainly in the following aspects: First, the application area is poorly adjustable. Specifically, the grease dispenser applies grease to the surface of friction parts of mechanical equipment through a grease gun. The nozzle size of the grease gun is not adjustable, and its application range is strictly limited. Since the friction parts of mechanical equipment vary in size, in order to ensure lubrication efficiency and coverage, operators have to frequently change the grease gun with the corresponding nozzle diameter for different lubrication points. Therefore, the equipment has poor versatility, which increases the complexity of grease application and reduces maintenance efficiency.

[0004] Secondly, the grease penetration effect is poor. Specifically, when the grease is applied to the surface of the friction parts of the mechanical equipment by the grease gun, due to the high viscosity of the grease and the fact that the grease injection process only relies on the surface application pressure, the grease is difficult to effectively penetrate into the key contact area inside the friction parts. As a result, the grease only accumulates on the surface of the friction parts and is wasted, while the actual internal lubrication needs cannot be met, which in turn affects the lubrication effect.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a grease applicator. When applying grease to friction components, the application area can be dynamically adjusted according to the actual size of the lubrication point, thereby accurately matching friction components of different specifications. It can achieve efficient coverage without changing the grease gun, significantly simplifying the operation process, greatly improving the versatility and maintenance efficiency of the equipment, and completely solving the application limitations of traditional fixed-caliber grease guns in different lubrication scenarios. This equipment applies a mechanical patting action simultaneously during the grease application process to the friction components. This causes the high-viscosity grease accumulated on the surface of the friction components to quickly penetrate into the key contact areas under the impact force, effectively avoiding surface accumulation and waste. It significantly improves the penetration effect and coverage uniformity of the grease, fundamentally ensuring the lubrication effect on the friction components.

[0007] To address the above problems, the present invention provides the following technical solution: A grease dispenser includes a grease reservoir and a grease gun. The top of the grease reservoir is provided with a pump unit that draws grease from the reservoir and pumps it out. The grease gun is connected to the pump unit through an oil delivery pipeline. The grease gun outlet is provided with an oil outlet pipe, and the oil outlet pipe port is provided with an applicator. The coating assembly includes a supporting circular plate with a grease reservoir inside the plate that communicates with an oil outlet pipe. A supporting pipe communicating with the grease reservoir is fixedly mounted at the end of the supporting circular plate. A fixed cylinder is fixedly fitted onto the outer wall of the supporting pipe. A first tapping plate is provided inside the fixed cylinder. A first sliding tube is fixedly inserted through the end of the first tapping plate. One end of the first sliding tube extends through the supporting pipe into the grease reservoir and is slidably and sealed to the supporting pipe. Several synchronously rotating tubes are provided circumferentially at the end of the supporting circular plate. One end of each rotating tube extends into the supporting circular plate and communicates with the grease reservoir. A swinging arc plate is fixedly fitted onto the outer wall of each rotating tube. A grease channel communicating with the rotating tube is provided inside the swinging arc plate. A fixed pipe is fixedly mounted at the end of the swinging arc plate. A second tapping plate is provided inside the fixed pipe. A second sliding tube is fixedly inserted through the end of the second tapping plate and is slidably and sealed to the swinging arc plate. The second sliding tube is connected to the grease channel.

[0008] As an optimized solution, the end of the supporting circular plate is fixedly provided with a connecting pipe that communicates with the grease reservoir, and the connecting pipe is fixedly connected to the oil outlet pipe.

[0009] As an optimized solution, the end of the supporting circular plate is provided with a sliding circular plate, which is slidably connected to the outer wall of the connecting pipe. The end of the sliding circular plate is provided with a plurality of rotatably arranged driven arc plates along the circumferential direction. The outer wall of the supporting circular plate is provided with a plurality of clearance grooves along the circumferential direction. The second sliding pipe passes through the clearance grooves and is fixedly connected to the driven arc plates.

[0010] As an optimized solution, a connecting rod is fixedly provided at the end of the sliding circular plate. One end of the connecting rod passes through the supporting circular plate, extends into the grease reservoir, and is fixedly connected to the first sliding tube. The connecting rod is slidably and sealingly connected to the supporting circular plate.

[0011] As an optimized solution, the outer wall of the first sliding tube is provided with a plurality of first grease passage holes at the position where it is located in the grease storage tank, and the outer wall of the second sliding tube is provided with a plurality of second grease passage holes at the position where it is located in the grease storage tank.

[0012] As an optimized solution, a plurality of reciprocating telescopic cylinders are fixedly provided at the end of the supporting circular plate, and the telescopic ends of the reciprocating telescopic cylinders are fixedly connected to the sliding circular plate.

[0013] As an optimized solution, the first striking plate is slidably and sealed to the fixed cylinder, and the second striking plate is slidably and sealed to the fixed tube.

[0014] As an optimized solution, a rotatable transition gear is fitted on the outer wall of the support tube, and a driven gear that meshes with the transition gear is fixedly fitted on the outer wall of the rotating tube.

[0015] As an optimized solution, the end of the supporting circular plate is provided with a drive shaft, the outer wall of the drive shaft is fixedly fitted with a drive gear that meshes with the transition gear, the end of the supporting circular plate is fixedly provided with a drive motor, and the output shaft of the drive motor is fixedly connected to the drive shaft.

[0016] As an optimized solution, one of the ports of the oil outlet pipe, the rotating pipe, the first sliding pipe, and the second sliding pipe is sealed.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. When adding grease to the friction components, the operator holds the grease gun and brings the fixed cylinder and fixed tube into contact with the friction components. The drive motor drives the drive shaft and drive gear to rotate reciprocally. Under the transmission of the transition gear and several driven gears, several rotating tubes rotate synchronously, thereby driving the swinging arc plate and fixed tube to swing back and forth. The second sliding tube and driven arc plate swing synchronously with the swinging arc plate. At the same time, the pump unit draws and pumps the grease from the grease tank. The grease enters the grease reservoir through the oil outlet pipe and connecting pipe. Part of the grease in the grease reservoir enters the first sliding tube through the first grease hole and is discharged. The remaining grease in the grease reservoir enters the first sliding tube through the rotating tube. The grease enters through the grease groove, then flows through the second grease hole into the second sliding tube and is discharged, thus applying the grease to the surface of the friction components. By controlling the reciprocating rotation angle of the drive gear by the drive motor, the reciprocating swing angle of the swinging arc plate can be adjusted, thereby adjusting the grease application area. When adding grease to the friction components, the application area can be dynamically adjusted according to the actual size of the lubrication point, thereby accurately matching friction components of different specifications. It can achieve efficient coverage without changing the grease gun, significantly simplifying the operation process, greatly improving the versatility and maintenance efficiency of the equipment, and completely solving the application limitations of traditional fixed-diameter grease guns in different lubrication scenarios. 2. During the application of grease, the reciprocating telescopic cylinder drives the sliding circular plate to slide back and forth, which in turn drives the connecting rod, the first sliding tube, and the first tapping plate to move back and forth. At the same time, the sliding circular plate also drives the driven arc plate, the second sliding tube, and the second tapping plate to move back and forth. The first and second tapping plates tap the discharged grease. This equipment applies a mechanical tapping action simultaneously while adding grease to the friction parts, so that the high-viscosity grease accumulated on the surface of the friction parts can quickly penetrate into the internal key contact area under the impact force, effectively avoiding surface accumulation and waste, significantly improving the penetration effect and coverage uniformity of the grease, and fundamentally ensuring the lubrication effect on the friction parts.

The drive motor 23 drives the drive shaft 20 and drive gear 21 to rotate reciprocally. Under the transmission of the transition gear 18 and several driven gears 19, several rotating tubes 13 rotate synchronously, thereby driving the swinging arc plate 14 and fixed tube 10 to swing back and forth.

The grease enters the grease tank 30 through the rotating tube 13, then enters the second sliding tube 11 through the second grease hole 29 and is discharged, thereby applying the grease to the surface of the friction component. By controlling the reciprocating rotation angle of the drive gear 21 through the drive motor 23, the reciprocating swing angle of the swing arc plate 14 can be adjusted, thereby adjusting the grease application area. When the device adds grease to the friction component, the application area can be dynamically adjusted according to the actual size of the lubrication point, thereby accurately matching friction components of different specifications. It can achieve efficient coverage without replacing the grease gun 4, significantly simplifying the operation process, greatly improving the versatility and maintenance efficiency of the equipment, and completely solving the application limitations of the traditional fixed-diameter grease gun 4 in different lubrication scenarios. During the application of grease, the reciprocating telescopic cylinder 27 drives the sliding circular plate 24 to slide back and forth, which in turn drives the connecting rod 28, the first sliding tube 7, and the first tapping plate 8 to move back and forth. At the same time, the sliding circular plate 24 also drives the driven arc plate 25, the second sliding tube 11, and the second tapping plate 12 to move back and forth. The first tapping plate 8 and the second tapping plate 12 tap the discharged grease. The device applies a mechanical tapping action simultaneously during the process of adding grease to the friction components, thereby causing the high-viscosity grease accumulated on the surface of the friction components to quickly penetrate into the internal key contact area under the impact force, effectively avoiding surface accumulation and waste, significantly improving the penetration effect and coverage uniformity of the grease, and fundamentally ensuring the lubrication effect on the friction components.
